IMPROVEMENT IN SCREENS FOR HEATERS.

Specification forming part of Letters Patent No. 38,210, dated April 2l, 1863.

.To all whom, it may concern.:

Be it known that I, WILLIAM G. BAKER, of New York city, of New York county, in the State of New York, have invented anew and useful Improved Screen for Steam and other Heaters; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyin g drawings, making part of 'this application.

My invention relates to an improvement in what are denominated screens77 of heating apparatus--that is,.the case which surrounds the coil or heating-surfaces of the heater, (either in steam, hotair, or other kinds of heating apparatus)and which is generally of cast metal, so formed, with perforations over its entire surface, or of open-work, as to admit of a free circulation through its openings of the surrounding air, in order that the latter may be heated by the heating-coil or other heating-surface which is within or back of the screens or screen, and by them partially hidden from View.

The object of employing the screen surrounding the coil, or other heatingsurface, (or partially surrounding it, where the coil sets against the wall,) is to hide the coil of steam or hot-air pipes and its fixtures; but since it is necessary that the surrounding air come freely in contact with` the coil by which it is to be warmed, it has been customary to cast the screen in the form of an ornamental grating, (somewhat similar to those employed for registers,) which would be sufliciently open through its entire surface as to admit of free contact of the airwith, and circulation around,` the heating-coil, while at the same time the said grating (screen) would sufciently hide from view the coil of pipes, and, sur- Inounted with a marble slab, for instance, would be rather ornamental than otherwise.

It is obvious that a heating-coil surrounded by a screen-such as known previous to my invention-will effect the heating of the surrounding air in the same mode as if the coil were employed without the screen.

My invention consists in making the screen which surrounds the heating-coil the means for producing a current of the air, being heated from the bottom of the coil up to its top, by making the screen a solid plane with an opening or series of openings near its bot tom edge, and another opening or `series of openings near its top edge, as hereinafter more fully explained. d

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation, referring by letters to the accompanying drawings,'forming part of this application, and in which- Figure l represents a perspective view of one of my improved coil-screens. Fig. 2 is another similar View, showing a modification of my improved screen. Fig. 3 is a front ele'- vation, and Fig. 4 a vertical section at the line x fr, Fig. 3.

In the several gures the same parts are indicated by the same letter of reference.

A is the screen, B the top slab of heater, and C the coil, rIlc screen A, instead of be* in g perforated all over, or through its central portion, as was customary previous to my invention, is made as a solid panel,and with a slot or opening, a, (see Fig. 1,) running along near its top edge, and another similar opening, b, near its lower edge. The effect of thus constructing the screen A is to cause the surrounding air to enter through the opening b and ascend through the coil and make its exit through the opening a, as illustrated by the red arrows in Fig. 4. It will be-seen that by this mode of operation, consequent to the peculiar construction of the screen, the particles of cold air (which are always near the floor) will enter at the bottom of the coil and be compelled to pass up through or by the entire coil before making their escape into the apartment again. It will be observed that, while my improved screen effects this very desirable new result, it also more effectually shields the coil from view, and is less costly in its construction than the perforated or grating screens now in use.

My improved screen is most admirably adapted, on account of its plain surface, to be made and ornamented in imitation of a piece of furniture, and may be thus, for many places, rendered much .more desirable than the ornamental gratings.

At Fig. 2 is shown a modification, in which,

steam or hot-Water pipes, of a screen which is constructed substantially in the manner described, for the purposes set forth.

In testimony whereof I have hereuntol set my hand and affixed my seal this 22d day ot October, 1862.
